Vernal Equinox

Real World Example

Imagine trying to balance a seesaw perfectly with one person on each end, but you can only achieve this balance twice a year. The Vernal Equinox is like that moment when the seesaw is perfectly horizontal, with neither side tipping, as it marks a day when day and night are of nearly equal length everywhere on Earth. Just as the seesaw finds its balanced point, the Sun's position directly over the equator during the Vernal Equinox ensures an equilibrium between the northern and southern hemispheres in terms of sunlight.
